Condition

As part of our ongoing quality improvement efforts, the E90 ECM part numbers
12711353, 12719704, 12731719 and 12740717 have been placed on restriction through
TAC.

Cause

This restriction is intended to assist GM Engineering with product feedback.

Correction
Prior to contacting GM Technical Assistance for part authorization, verify the concern is not associated with the
following:
Vehicles with DTCs P062B and/or P060C set in the ECM.
If either or both of the DTCs are set perform the following:
Step 1: Verify ECM has the latest software, reprogram and re-evaluate as needed.
Step 2: Clear all DTCs, perform a global reset and re-evaluate.
Step 3: If either/both DTCs do not not reset promptly after the previous step , do not attempt to replace ECM as this
will not resolve this issue. (Additional information for 2023-2025 Model Years available in latest version of PIT6110) If
either of the DTCs do reset promptly after the previous step than an ECM should be ordered.
If the previous concern is not applicable, be sure to have the SI document that has led to ECM replacement
available and be prepared to review diagnostic steps leading to ECM replacement with the TAC agent.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
